High-performance sound and a slim, elegant design

The Mythos STS SuperTower is a more compact sibling to Definitive's top-of-the-line Mythos ST, and likewise delivers impressive, high-end home theater sound. In fact, Stereophile's Wes Phillips wrote, "It just may be the best loudspeaker I've heard for $3,000/pair" (August 2008 issue). It features a sleek aluminum cabinet and some of Definitive's most advanced components and technologies. But what really sets the Mythos STS apart from typical speakers is the SuperCube® powered subwoofer built right into the cabinet. It allows this speaker to generate startlingly deep bass, for big home theater sound.

High-tech components and design for exceptionally detailed sound

Closeup of the tweeter and midranges.

Near the top of the cabinet are two 4-1/2" midrange drivers flanking a 1" dome tweeter, all acoustically isolated in their own sub-enclosure to prevent interference from the bass drivers (see cutaway shot in more photos). Each midrange features Definitive's Balanced Dual Surround System (BDSS) technology, which employs rubber surrounds on both the outer and inner edges of each speaker cone, for more stable, precise motion resulting in exceptional clarity. The pure aluminum dome tweeter has a special ceramic coating, so you'll hear loads of sonic detail without the edginess of lesser tweeters.

Powerful bass built right into the cabinet

The lower section of the cabinet holds a 5" x 10" racetrack-shaped woofer reinforced by two bass radiators. This combination creates a total surface area that's actually greater than that of a traditional 12" woofer, but the three-driver approach provides better low-frequency control, speed, and detail. A built-in 300-watt amplifier powers the subwoofer, delivering massive bass that eliminates the need for an external sub. Aside from saving you some floor space, the built-in subwoofer ensures balanced system sound because the bass is already perfectly blended with the mids and the highs. The subwoofer also has an adjustable volume control so you can fine-tune the bass to suit your room or taste.

Each speaker has an aluminum cabinet and a polished granite base.

Gorgeous aircraft-grade aluminum cabinet

Definitive took a step away from the traditional look of boxy floor-standing speakers, and built the Mythos STS's slim, curved cabinet using contemporary design principles. The enclosure is made of black hand-polished aluminum, and rests on a polished granite base to ensure total rigidity and stability. Hooking it up is as simple as running one set of speaker wires from your amplifier or receiver to the speaker.

Build a complete home theater system using perfectly matched Definitive Technology center and surround speakers. The Mythos STS pairs well with Definitive's Mythos Three center channel and Gem surrounds.

Got wire?

Did you know?
Your new speakers will probably sound better after several weeks of use than they do right out of the box. That's because the material surrounding the woofers will loosen up, allowing the drivers to move more fully. Definitive Technology estimates a break-in period of 24 to 48 hours of playback before the speakers will deliver optimum sound quality. For more information and helpful tips, check out this article from Definitive's website about conditioning your speakers.

Floor-standing speakers  still standing tall

Sure, floor-standing tower speakers buck the industry trend toward smaller, visually inconspicuous speakers, but they're hard to beat if great sound is your primary goal. Tower speakers produce powerful sound with excellent bass, making them a great choice for serious music lovers and for folks who want high-impact home theater.

I will start off with saying I have owned these speakers for about two years, very happy with the overall quality. Made the step up from Klipsch Reference Speakers. I took some time for my ears to adjust to these gems from the monstrous bass and explosiveness the Klipsch line offered, they are still a guilty pleasure. Anyways, the bass is great and tight, highs clean and non fatiguing. Very detailed mid's and would recommend to anyone with a "medium" to "slightly" large room. They speakers seem to play nice with the many receivers I own. Currently run with NAD C 356BEE. When auditioned everyone I know is blown away!! Recommend these speakers and the amp.

Pros:Amazing reproduction of live music from top to bottom, especially surprised with the performance from the midrange drivers considering their size.

Definitive Technology Mythos STS SuperTower®

Beautiful design, clean rich sound, one of the top 10 Greatest audiophile speakers; under $3,500; CNET 2009. Boxed well. beatiful black granet base. I layed the speakers across the coach arms so I could assemble the stone bases, They come with specialize feet for hard wood or carpet. The blend well into my room only the sound being the center of focus.

Pros:In the price range this is an excellent quality speaker the sound filles the space with the built in powered subwoofers. You can put them closer to the wall then some othe designs, the look great in the room with out being the visual focus in the room.

Cons:They are actually sold by each so remember to buy two, Just under $3,000 for the pair.

Exceptional sound

The sound these speakers produce is truly amazing. The built-in subs give it a sound and presence that I haven't heard in similar sized speakers. I shopped at a number of audio shops and listened to a number of speakers, but to me these reproduced music the most faithfully without a hint of strain. Additonally, put in a home theater setup, they can produce startling impact when called for. The combination of musicality and an eagerness to produce all the sounds called for in a home theater setup, make these speakers real winners.

These things make you shake your head in amazement.

I shopped around for speakers for a full year. I wanted a full range tower and, being a man's man, I wanted a BIG full range tower. I've seen these "lifestyle speakers for a while and always passed them by thinking they were all looks & not much substance. After all, at only about 6" deep, how much bass could they possibly produce? Well, let me tell you... plenty. Not only that, they are extremely well balanced top to bottom.

You will have your friends looking under the sofa for the hidden subwoofer in the room. Pinpoint imaging. Lifelike vocal presentation. Amazingly dynamic. These speakers are truly unbelievable! I've been a fan of Def Tech since their inception. The BP10 was my introduction to truly balanced, full range sound. But with the Mythos STS speakers, they have truly come up with something special.

Anything more enjoyable is illegal

I wanted these for over a year, finally pulled the trigger and I can't stop smiling. Bass is rich and deep, amazingly so especially when you see the size of the sub-woofers. I heard these powered by a 50 watt integrated amp and was sold immediately. I own a full Definitive home theater set up but I enjoy just listening to the STS towers on their own. My speakers are still green but I am still impressed by their sound, I can't imagine the level of detail that they are capable of but I am looking forward to finding out. I don't regret a single penny that I spent on these

Supercalifragilisticexpialidocious

Some audio mfgs. do well with the advertisment of their products only to be sold a mid-level piece of equipment. I was unfamiliar with definitive technolgy until last year when I began outfiting a theatre. Their products are the rule and should be purchased imidately so one does not waste time and money on the standard.

Aurally and Visually Beautiful

Beautiful sound

Written By CK, Martin, TN on Thursday, September 16, 2010

I bought these to replace my Bose Acoustimass system almost a year ago. Much fuller sound than the Bose. Makes my living room more like a theater than it has ever been. I worried my wife would complain about replacing the 'virtually invisible' Bose cubes with these towers. She loves them too.

Product Research

Overview: The Definitive Technology Mythos STS SuperTower is
a tower loudspeaker with a built-in powered subwoofer. The Mythos STS SuperTower
design offers a truly full-range loudspeaker that combines the accuracy,
imaging, and detail retrieval of a monitor speaker with the depth, dynamics, and
bass output a separate powered subwoofer into one visually attractive,
small-footprint enclosure. The Definitive Technology Mythos STS SuperTower
utilizes a 1-inch pure aluminum dome for extended highs and two 4.5"
high-definition cast-magnesium basket midranges for smooth sounding vocals. The
Mythos STS SuperTower also features a "racetrack" shaped carbon fiber active
driver powered by a built-in 300-watt Class-D amplifier and pressure-coupled to
two "racetrack" shaped low-bass radiators equal to the surface area and bass
output of a 12-inch woofer but with far greater control, definition and speed;
eliminating the need for a separate subwoofer. The STS SuperTower features a
and-polished gloss aircraft-grade extruded aluminum enclosure with proprietary
damping technologies and polished granite base to ensure total rigidity and
stability. The Mythos STS SuperTower has been engineered for music listening and
home theater enjoyment.

Break-In Period: The Mythos STS SuperTower will sound good
right out of the box; however, an extended break-in period of 40-60 hours or
more of playing is required to reach full performance capability. The break-in
period allows the suspensions to work in and results in full bass, a more open
midrange, and smoother high frequency reproduction.

Built-in Powered Sub

Powered Subwoofer: The 5 x 10-inch "racetrack-shaped"
polymer/carbon composite subwoofer is powered by a built-in 300-watt Class D
amplifier and pressure-coupled to two 5 x 10-inch "racetrack-shaped" planar
low-bass radiators for a total bass radiating area greater than a 12-inch
woofer; but with far greater control, definition, and speed. A pair of STS tower
loudspeakers is like having two 12", 300-watt powered subwoofers in your room
without taking up anymore floor space. The result is bass that is deep, powerful
and impactful while at the same time having tight, controlled, and accurate
response. The built-in powered subwoofer also provides the following features.

Auto Turn-On: The Mythos STS's built-in active power
subwoofer section must be plugged into an electrical socket using the
supplied 10' AC cord. The Mythos STS has a special circuit which
automatically turns the powered subwoofer section on when a signal is fed to
the loudspeaker and turns off when there is a no signal (for 1-hour).

LED: An LED on the back-panel will light up when a
signal is sensed and the amplifier turns on. The LED will automatically
turn-off when there is no signal (for 1-hour).

Built-In Crossover: Definitive's engineers have
perfectly adjusted the crossover and phase between the subwoofer and main
speaker sections of the Mythos STS SuperTower to achieve seamless blending
and life-like sound.

Note: Please not that there are no controls to vary
the crossover points or phase because these have been factory calibrated
and set to provide perfect blending.

Level Control: The Mythos STS SuperTower has a
bass-level control which allows you to tune the output level of the built-in
powered subwoofer section to match your room and personal listening
preferences.

Protection Circuit: To prevent accidental damage to the
subwoofer built-in the Mythos STS SuperTower from overdriving the system,
the built-in powered subwoofer section features an internal overload
protection circuit, which will turn the powered subwoofer off or down when
overdriven or overheated and will then resume normal operation after a few
minutes.

Enclosure Design

Curved Extruded Aluminum Enclosure: The
enclosure is extruded aluminum with internal ribs for stiffening purposes.
Strips of damping material are adhered to the inside of the extrusion to
suppress ringing. The baffle is "Polystone" a dense and non-resonant
mineral-filled polymer material that is slightly oversized and is force-fit into
the extrusion "mouth" to prevent the aluminum from ringing. The midrange/tweeter
array is isolated from the woofer enclosure by two pieces of MDF. Both woofer
and mid/hi enclosures are sealed. The slim,
curved shape of the enclosure reduces diffraction contributing to the ST's
broad imaging and deep soundstage.

Mounting Options

Granite Base with Adjustable Feet: The
granite base combined with the heavy Toroidal transformer mounted on the bottom
plate of the loudspeaker's enclosure provides a low center of gravity for
superior stability. The base incorporates 5 adjustable-height metal feet that
may be fitted with either smooth furniture glide tips for wood and ceramic
floors, or spikes for carpeted floors.

Applications: The precise accuracy, wide-range response, and high impact dynamic range of the
Mythos ST allow you to use the speaker in most home audio/video system's
ranging from a 2-channel music-only to a 7.1 channel home theater system.
When used as a stereo pair, simply connect it with speaker wire as one would any pair of speakers; there is
no benefit to using the low-level LFE inputs. When using the ST in a
multi-channel system there are two options.

Connect speaker wire as in a stereo system; set bass management as Front=Large, Subwoofer=None

In addition to speaker wires connect low-level cables from the LFE/Subwoofer output of the
receiver/processor to the LFE inputs of the ST (Y connector is usually
required). Set bass management as Front=Large, Subwoofer=Yes. The benefit of
this hook up method is that one now has the ability to control the level of
the LFE channel relative to Front L&R bass.

Placement: The Mythos STS SuperTower loudspeaker can be used as a Main
or Surround speaker.

Fronts: When used as a front main speaker, you should create an
equilateral triangle between the speakers and your listening area. The
speakers should be angled toward the center of the listening position for
brighter, clear, sound with a sharper focus and a more solid central image.
Pointing the speakers straight forward, parallel with each other , will
result in a warmer less sharply focused sound. To get the best possible
imaging and most even tonal response, avoid placing the speakers less than
3-feet (1-Meter) from your room's walls.

Surrounds: When used as rear or surround speaker, the Mythos ST may be
located on the side or behind the listeners. When used on the sides, take
care never to locate the speakers forward of the listeners. When the
side/rear speakers are close to the listening position, do no aim the
speakers directly at the listeners.
